Genetic Analysis of Ewe Productivity Traits in Baluchi Sheep
The present study was carried out to estimate (co)variance components and genetic parameters for some productivity traits of Baluchi ewes. The data were collected during a 31 year period (1984-2014) at the experimental breeding station of Baluchi sheep, which is located in north-east of Mashhad, Iran. The analysis was based on 14030 records of lambs and 4371 records of ewes. Investigated traits...
متن کاملEstimates of genetic parameters for growth traits in Kermani sheep.
Birth weight (BW), weaning weight (WW), 6-month weight (W6), 9-month weight (W9) and yearling weight (YW) of Kermani lambs were used to estimate genetic parameters. The data were collected from Shahrbabak Sheep Breeding Research Station in Iran during the period of 1993-1998. The fixed effects in the model were lambing year, sex, type of birth and age of dam. Number of days between birth date a...

متن کاملestimates of genetic and phenotypic parameters for composite reproductive traits in baluchi ewes
records of 2593 baluchi ewes, obtained from baluchi sheep breeding station in abbas abad, mashhad, were used to estimate genetic parameters for total weight of lamb weaned per ewe joined (tww/wj) in different parities. estimates of heritability for tww1/ej, tww2/ej, tww3.ej and tww4/ej were 0.112 ? 0.030, 0.028 ? 0.030, 0.075 ? 0.060 and 0.135 ? 0.120, respectively. direct additive genetic corr...
